Kexec is a feature that allows to boot kernels from a working kernel. It was originally intended for use by kernel and system developers who had to reboot several times a day. Soon, system administrators for high-availability servers found use for it as well. As systems get more and more advanced, and boot times get longer, end users can now benefit from it.

I knew we'd get one or two people wading in with 'OpenSolaris does this, Linux is just copying!' I'm also not too interested in what has been available internally either, as it kind of negates the word open. But I digress.
Unfortunately, Kexec was committed around about 2002/2003. It's mainly been used by kernel testers over the years because it makes things far easier, but it's been used by many for a while to get new kernels and updates running on their servers and it's gained more attention in these times of 'instant-on' access.

Yeah, it's really a shame that Sun's not just throwing shit against a wall and looks what sticks, like the Linux folks do, and prefers for things to be designed and work stable enough out of the box... >_>
And since we're on topic, regarding your highlighting bullshit, I'm certain various BigCo's related to Linux kernel development are holding back a lot of code until stabilization, too. So don't give us that "Hurrrrrr, OpenSolaris!" bullshit. Then again, why am I arguing with YOU? It's like talking to a wall.
So what? Sure wasn't being used much or promoted outside kernel testing.

Hmm, i don't think it's about "We were first!" from the Opensolaris side. It's just the impression, that the introduction of PSARC 2008/382 into OpenSolaris led to the thought "Heck, we had the infrastructure for doing something similar in Linux for quite a time. Let's make it available to end users" and perhaps "Shame on us, that we left the first availability in a standard distribution to the Opensolaris commuity".

If I remember correctly, Solaris used CDE and would still be using CDE (nice but not very modern) if it weren't by GNOME/KDE which were developed once Linux became alive. What could be possibly wrong about using some technology the "competition" already has if it, somehow, improves the software? Quit bitching, what you say doesn't really matter in this world (applies to me too).

Wow, so OpenSolaris announces Fast Reboot (which was in the works and available internally for a while) and whoop Linux suddenly releases their internal stuff, too. What a coincidence.
